Well you changed 3 things so start with those...

Scan for codes first obviously.

Make sure 3.5 bar tmap flash option is checked in flash options.

Pressure/smoke test for vacuum leaks.

Make sure plugs/coils installed correctly.

Make sure the injectors are disabled at idle and tuned correctly.

sounds awesome..

read codes

you have a custom tune for the port injection correct?

either tmap not set correctly or.issues with plug install likely.
